1.5 ACPI Features
The Advanced Configuration and Power Interface (ACPI) specification defines a flexible and
abstract hardware interface that provides a standard way to integrate power management
features throughout a computer system, including its hardware, operating system and
application software. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
interface for configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
appropriate Windows operating systems. For detailed information regarding OS support, refer
to the Supermicro website.
1.6 Power Supply
As with all computer products, a stable power source is necessary for proper and reliable
operation. It is even more important for processors that have high CPU clock rates where
noisy power transmission is present.
This motherboard accommodates a 24-pin ATX power supply. Although most power supplies
generally meet the specifications required by the CPU, some are inadequate. In addition, one
12V 8-pin power connection is also required to ensure adequate power supply to the system.
Note 1: The X13SAZ-F/Q motherboard alternatively supports an 8-pin 12V DC input
power supply at JPV1 for embedded applications. It provides up to 360W power input
to the motherboard. Keep the onboard power usage within the power limits specified
above. Over current power usage may cause damage to the motherboard.
Note 2: Connect both the 8-pin DC power at JPV1 and JPW1 to make sure the CPU
receives enough power for normal operation when using the ATX power supply
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or above.
